The 2015 NFL season kicks off next Thursday, September 10, but most of the football action will be on Sunday September 13. That will also be the date when two of the fiercest division rivals of the NFC North in the Chicago Bears and the Green Bay Packers play their first game of 2015 against each other. The Chicago Bears are historically known for their great defense, which resulted in two championships, but since 2012 the team has fielded arguably their two worst defenses in the history of the franchise, which resulted in a mediocre 5-11 record in 2014. Meanwhile, the Packers won the division in 2014, finishing 12-4 and bring this season arguably one the best rosters in football into 2015 led by MVP quarterback Aaron Rodgers.

Chicago Bears tickets on the secondary market are always in high demand and for their season opening game at Soldier Field against the Packers, Bears tickets are the most expensive of the season according to TicketIQ, averaging $528.49 on the secondary market. That is a 50% increase compared to the overall average for Bears tickets at Soldier Field in 2015 and one of the most expensive games overall in the NFL this season. The cheapest ticket to get into this game is priced at $192.

The two teams will then meet again in Week 12 on Thanksgiving night. Not only will it be a primetime holiday game between these two rivals, the Packers will hold a ceremony for the jersey retirement and induction into the Packers Hall of Fame for Brett Favre at halftime. It’s no surprise then that the game is the most expensive in Green Bay this season with an average price of $464.87 and a get-in price of $247.

In their long history dating back to 1921, the clubs have played each other 190 times with Chicago currently leading the series 93-91-6. However, the Packers have been the more dominant team as of late and have won their past three meetings, including the last time they played at Soldier Field where the Packers embarrassed the Bears on their home floor 55-14 last November. Green Bay quarterback Aaron Rodgers tied the NFL record for most touchdown passes (6) in the first half alone. It was the worst Bears loss to the Packers since the 1962 season and the highest point total since 1945.
